Reefer 170 plumbing

[Sharkbait13]

Hello everyone,
I just received a reefer 170, and I got everything built no issue. However, my main drain is taller than my emergency? This is my first sump system, so I apologize in advance. But has anyone had a similar issue? Or how do I solve this?

Use the tail tube on the Emergency drain.

So with the tube on, is it taller than your emergency??

Use the tail tube on the Emergency drain.

So if I do that, that the main drain itself is shorter, but the pvc tube doesn’t go to the bottom

This is how big the difference is

The tall one goes on the overflow. The short one with the large silencer pipe goes on the down flow that runs to you threw your adjustable flange valve. If for some reason the shorter main return would clog, water will go down the taller emergency tube.

I am not sure without a clear picture but my main drain is in the bottom of the tank. The other is near the top which is an anti siphon protection during any power or pump failure
